Question

I’m trying to match all the dates that are found in a string, here is the function

$description = "1999 2008 1998";

if(preg_match("/[12][0-9]{3}/", $description, $matches)){
   print_r($matches);
}

The problem is that only the first date is returned which is 1999, I actually want to match all dates.

What should I change in the regex?

Answer 1

Do you mean this?

<?php
$description = "1999 2008 1998";

if(preg_match_all("/[12][0-9]{3}/", $description, $matches)){
   print_r($matches);
}

only difference is preg_match_all instead of preg_match.
